广义洛伦兹变换群的子群及其几何不变量

Subgroups of the Group of Generalized Lorentz Transformations and Their Geometric Invariants

G. Yu. Bogoslovsky

摘要:

证明了广义洛伦兹变换群是平坦芬斯勒事件空间的相对论对称群。Finsler事件空间是Minkowski空间的推广,它起源于初始规范对称性的自发破缺和各向异性费米子-反费米子凝聚的形成。广义洛仑兹不变性原理使我们能够精确地考虑凝聚态对基本场动力学的影响。特别地,相应的广义狄拉克方程原来是非线性的。我们找到了广义Lorentz对称群的两个非紧子群及其几何不变量。这些子群在构造这类方程的精确解中起着关键作用。

英文摘要:

It is shown that the group of generalized Lorentz transformations serves as relativistic symmetry group of a flat Finslerian event space. Being the generalization of Minkowski space, the Finslerian event space arises from the spontaneous breaking of initial gauge symmetry and from the formation of anisotropic fermion-antifermion condensate. The principle of generalized Lorentz invariance enables exact taking into account the influence of condensate on the dynamics of fundamental fields. In particular, the corresponding generalized Dirac equation turns out to be nonlinear. We have found two noncompact subgroups of the group of generalized Lorentz symmetry and their geometric invariants. These subgroups play a key role in constructing exact solutions of such equation.
